Dysregulation of lipid mediators derived from polyunsaturated fatty acids may contribute to this inflammatory response in the brain of patients with AD, yet the literature has not yet been systematically reviewed. A systematic search was conducted in Medline, Embase and PsychINFO for articles published up to April 22, 2024. Papers were included if they measured levels of lipid mediators and/or enzymes involved in their production in <em>post-mortem</em> brain samples from patients with AD and control without neurological disease. A total of 50 relevant studies were identified. Despite heterogeneity in the results, pro-inflammatory lipid mediators, including 5-, 11-, 12- and 15-hydroxyeicosatetraenoic acid oxylipins and prostaglandin D2, were significantly higher, while anti-inflammatory lipoxin A4 and DHA-derived docosanoids were significantly lower in brains of patients with AD compared to control (16 studies). Thirty-seven articles reported on enzymes, with 32 reporting values for enzyme level changes between AD and controls. Among the 32 articles, the majority reported on levels of cyclooxygenase (COX) (18/32), with fewer studies reporting on phospholipase (8/32), lipoxygenase (LOX) (4/32) and prostaglandin E synthase (4/32). Enzyme levels also exhibited variability in the literature, with a trend towards elevated expression of enzymes involved in the pro-inflammatory response, including COX and LOX enzymes. Overall, these results are consistent with the involvement of neuroinflammation in the pathogenesis of AD measured by lipid mediators. However, the specific contribution of each lipid metabolite and enzymes to either the progression or persistence of AD remains unclear, and more research is required.</div></div>","PeriodicalId":72454,"journal":{"name":"Brain, behavior, & immunity - health","volume":"43 ","pages":"Article 100938"},"PeriodicalIF":3.7,"publicationDate":"2025-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11782888/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143082193","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In the present study, we have investigated whether a possible early deterioration in the blood-brain barrier (BBB) may facilitate the infiltration of immune cells to the brain parenchyma, which may contribute to these pathogenic events. In this study, conditional knock-in <em>Scn1a</em>-A1783V mice and their controls were used at the postnatal day (PND25): (i) to compare their levels of several immune cell populations in the bone marrow and blood; and (ii) to analyze several BBB proteins, as well as the occurrence of immune cell infiltration and endogenous immunoglobulin G (IgG) extravasation into the brain parenchyma. Our data revealed an elevation in the number of neutrophils in the blood of DS mice, but not of B- and T-cells, despite the levels of these immune cells were significantly reduced in the bone marrow. The elevated number of blood neutrophils did not apparently originate their infiltration into the hippocampus of DS mice as an immunofluorescence analysis indicated, and the same happened in B- and T-cells. However, the levels of endogenous IgG in this brain structure were significantly elevated in DS mice compared to controls, directly indicating the occurrence of extravasation into the brain parenchyma and indirectly that the BBB in DS mice may be relatively affected, a fact confirmed by the reduction in the levels of BBB-related proteins such as ZO-1 in these mice. In conclusion, our results support the occurrence of certain degree of deterioration in the BBB in DS, which may facilitate the infiltration of immune cells to the brain, then contributing to the pathogenesis in this disease.</div></div>","PeriodicalId":72454,"journal":{"name":"Brain, behavior, & immunity - health","volume":"44 ","pages":"Article 100955"},"PeriodicalIF":3.7,"publicationDate":"2025-01-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143377216","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
